additional options/OVERRIDE_APP_HOST option removed from the UI or doesn't work

[kyteinsky]

Describe the bug

The additional options UI has disappeared from the UI, maybe a regression from this PR: #705. Going back a few commits (4074fd8), it can be set in the UI but it doesn't work still. "additional_options" is not available here in the deploy config:

app_api/lib/Service/AppAPICommonService.php

Lines 48 to 50 in 0425db3

	if (isset($deployConfig['additional_options']['OVERRIDE_APP_HOST'])) {
	return $deployConfig['additional_options']['OVERRIDE_APP_HOST'];
	}

more testing is required to rule out the php cache and find the exact point of the issue, if additional option was never inserted in the DB or if it wasn't fetched properly.
